Description

DC water heating element is screwed directly through a threaded opening in a tank wall or through a matching pipe coupling or half coupling. Sizes of screw plug heaters are available with 1", 1-1/4", 1-1/2", 2", 2-1/2" pipe threads. A wide selection of screw plug sizes, kilowatt ratings, voltages, sheath materials, terminal enclosures and thermostats makes these compact heaters ideal for all types of applications.

We can use the sun's solar energy directly for domestic hot water heating systems. But we can also use the DC power generated from photovoltaic panels to power a DC Water Heating Element without using the mains electricity.

Heating water directly using a low wattage DC water heating element together with either a wind turbine generator or photovoltaic panel (with or without a battery bank) is commonly used in diy solar power system.DC water heating elements along with a pv array can even provide heated water under low irradiation or bad weather conditions, as the only limit to how hot the water becomes depends on how much energy a heating element can deliver into it.

These low voltage DC water heating elements can be powered using solar, wind, or battery, they can be powered directly from a single solar panel or pv array to heat up water with DC electricity.

DC immersion water heater element come in different voltages ranging from 12v to 48v, but you need to buy the one which is rated for your system voltage in order to sufficiently preheat your domestic hot water.

Features and advantage

DC 48V Electric Water Heating Element adopts stainless steel tube coat, modified magnesium oxide powder, high-performance nickel-chromium electrothermal alloy wire and other materials. This series of products can be widely used in heating water, oil, air, nitrate solution, acid solution, alkali solution and low-melting point metals (aluminum, zinc, tin, Babbitt alloy). DC 48V Electric Water Heating Element has good heating efficiency, uniform temperature, high temperature resistance, corrosion resistance and good safety performance.
